So, with this article, we will elaborately understand the rule of automation testing in the modern Agile development process. We will also go through some of the best practices that can help modern developers and testers improve the efficiency of their automated Agile development test bench.

Understanding the Basics of Automation Testing

While executing automation testing, the testers use specialized software tools and scripts to automatically run the test cases and verify the expected outcome of the software app. Automated tests aim to run repetitive and time-consuming manual testing tasks including functional testing, regression testing, and performance testing.

While running automation testing, the developers have to use special test scripts also known as automated test scripts to simulate user interactions within the application. It also allows the system to simulate human interactions like clicking buttons, filling out forms, and many others. Using these test scripts, the developers can identify the defects and ensure the reliability of the software to ensure continuous integration and delivery.

Although the automation test scripts are predetermined, the developers have the liberty of making significant changes in these data to ensure that the test reports are customized according to the project requirements.

Some major benefits of automated testing include testing efficiency, faster feedback on code changes, and improved test coverage. It also allows the execution of test cases consistently and repeatedly.

However, we would like to remind the developer that despite automated testing being an effective way of running test cases, it is not advisable to automate all the testing instances. The best approach is to maintain a proper balance between automated testing and manual testing.

Exploring Agile Development

Agile development is an incremental and iterative approach to software development. It prioritizes collaboration, flexibility, and customer satisfaction. This development process also emphasizes adaptive planning, rapid delivery of functional software, and the ability to respond to changing requirements throughout the development process.

Modern Agile methodologies like Kanban or Scrum promote close collaboration between cross-functional teams, delivery of small incremental improvements, and frequent assessments of the software in short time frames also known as sprints.

The ultimate goal of implementing Agile methodologies is the promotion of continuous value, quick delivery, and the ability to respond to changing market or project requirements quickly. Let us now take a brief look at some of the crucial features present within Agile methodologies:

●      Adaptive Planning

Agile projects embrace changes and regularly reassess the app priorities. This approach allows the development teams to adapt to evolving requirements and also respond to customer feedback throughout the development process.

●      Iterative Development

Modern Agile practices follow an iterative approach with short development cycles known as sprints or iterations. In this case, each iteration results in a potentially shippable product increment.

●      Cross-Functional Teams

Agile development actively promotes collaboration among cross-functional teams including testers, developers, and business stakeholders. This collaboration fosters effective communication and shared responsibility within the application development life cycle.

●      Involvement of Customers

In modern app development practices, constantly involving the customer is crucial for the success of the app. Agile methodologies prioritize customer feedback to ensure that the delivered product meets customer expectations and also provides value.

●      Backlogs and User Stories

Agile products use user stories to define features from an end user’s perspective. These stories are organized in a product backlog to allow teams to prioritize and plan work based on business value. This approach also allows the application to stay ahead of the competition by providing a more customized end-user experience.

All the above features collectively contribute to Agile development’s ability to deliver high-quality software that meets customer needs. It also allows the entire app development process to maintain flexibility and adaptability throughout the development and testing process.

Analyzing the Role of Automation Testing in Agile Development

Automation testing in Agile development streamlines the testing process to allow rapid and continuous delivery of software increments. This process also helps to accelerate the feedback loop to ensure faster delivery and also helps maintain the quality of the product throughout the frequent iterations.

Moreover, automation testing also helps simplify regression test cases so the teams can quickly catch up and address issues swiftly. This approach in turn promotes agility in the development life cycle.

Let us now understand some of the crucial areas of Agile development that benefit a lot from the integration of automated testing practices:

1.    Accelerating Feedback

The integration of automation testing with Agile development enables continuous testing and swift test cycles. This provides rapid feedback on software changes and helps the app developing and testing teams to identify and address crucial issues promptly.

2.    Continuous Integrations

Modern testers can seamlessly integrate automated tests into CI/CD pipelines. So, they can ensure that all the code changes are automatically tested. This approach promotes a more reliable and efficient development process for the app-developing companies.

3.    Quick Iterations

Automated Agile testing cycles enable faster execution and thorough coverage of the application that is currently being developed. It also allows the teams to iterate quickly and release softer increments more frequently in line with Agile principles. It is highly beneficial for modern applications that undergo frequent updates.

4.    Enhancing Collaboration

Using automated tests, the testers can create a common reference point for developers, testers, and other stakeholders. This approach helps foster collaboration and a shared understanding of the software’s requirements that is currently being developed.
